It will depend on the value of the exclusive car and the combined value of the other cars inside. Typically $8 to $15 USD. The box is not in the best condition so it will be towards the lower end in value. There is a car inserted in reverse though so an 'error' collector may pay a premium for that status.
Milton is correct about the values.
There is one certain variation in there. The 70 Chevelle. On the card it came orange or brown flames. In your picture it looks brown.
The other one that is interesting is the Acura NSX, the yellow casting. If it is a gray interior instead of a chrome, that is another one that may have some value.
Those 2 may boost it to $10, but the condition will be a an issue.
